To all whom it may 50mm:

Be it known that "I, EiENRY F. BitoiiMAN;

aeitizen of the United States, residing at Battle Creek, inthe county ofCalheun and State of Michigan, have invented 1 certain new and useful Improvements in Four-Pace Width Tubular Plate Presses; and I herehy declare that the following is a fuilflcleary and exactdescription thereof, reference be- 1O ing had to the accompanying drawings,

which form part of th'isjspecification.

This invention an improvement in retary web printing presses of .theslnglepage tubular plate type disclosedfl'in invPatents Nos. SGTQQSOofUctOber 1, 1907 and 125M008; of September 11, 1 917HThe ob} ject of this invention isto produce apress,

such as shown in my firstmentioned patent,

capable of printing a iour-page wideweb,

as suggested in my. second patent, butwith out the necessity 1 of employing staggered impression mechanisms; and I accomplish this by so constructing the type-cylinders of t' i the press that-they are enabled to each carry tour or more single-page tubular plates without springing, or bulging when ro- 1 tated at high speed or-[under impression pressure.

mediate hearing whereby such cylinderiseiiectually prevented from springing .or bulg -i it ing at high speed, or from. yielding und high impression pressures; and thereby I am i ahleto constructa single-page"tubular plate press in which each platecyl nder can carry four or more single-page tubular-plates arranged endto end; and bywhich four 'or' more page widewebs may beprinted with out slitting such websfiprior to printing;

and inlwhich equal margins can be leftbe-l tween the. adjacent page side by I side ima pressions transversely of the web. r i This invention iurther enables a singlepage-Uubular-platecylinder to be made four or more pages wlde without.multiplicat on of printing mechanisms, such as is required summarized' in the in this invention eaeh ftypeicylinder is Fig. 3. provided with anauxiliary central or intera.

1 Minor objects and advantagesof the invention will be hereinafterreferred to in' the detailed description of the invention.

Twill explain the invention with reference tials of the invention and the novel features Of construction and novel combinations of parts 'for-whichjprotection is desired are claims.

In said drawings:

Fig. dis a transverse section on theline Fig, 5 is aperspectiveview of an intermediate plate-cylinder-hearing detached.

The plate cylinder 1 is adaptedto carry four or more single-pagetubular plates P.

such as shown in myPatent No. 979,919 of December 27, 1910 four or" suchpla tes being shown; This plate cylinder 1 is journaled in end bearings I which are so constructed as to permit the singlepage tubular plates P to he slipped endwise over the hearing into position on the plate cylindery or oli the plate cylinder, as explained insaid 'Patent Beside the plate: cylinder and cooperating .therewith is an impression cylinder 2,

which is suitably journaled in or onthe main frame and is adapted to coact with the plates on the plate cylinder to. print a web or sheet of paper passed.thereb'etween.

' The "plate and i inpression cylinders are intergeared many suitable way so thatthey will rotate at the proper relative peripheral speeds and in proper time. Eorfenaiiiple theymight be intergeared asfindicatedin my Patent No. 1,223,025 oifAprii 17, 1917.

Preferably the drive is of such construction that the plates P can he slipped endwise over the bearings and on or off either or both ends of the cylinder 1. The particular gearing between, or mechanism for driving, such cylinders forms no part of the present invention a'nd is not claimed herein.

' Owing to the small diameter of the plat cylinders for single-page tubular-plates, at highspeeds such cylinders if more than two pages long have a tendency to springer bulge at the center, such tendency being accentuated by the impression pressure, and this seriously affects the operation of the printing mechanism and the uniformity of the product. I found that such plate cylinders made out of solid hard steel if more than two pages long would thus spring at high speeds. Many attempts have been made toovercome this difiiculty, but heretofore none h'ave been practically. satisfactory; but

. present invention I have provided a means to overcome or prevent such springing or yielding of s uch plate cylinders and am enabled to make them four or more pages wide and to hold them accurately to their work, and prevent springing thereof either at high speeds or under high impression pressures. I

In the present invention each plate cyl1n- :der 2 fora four or more page wide press is ,made' in two or more transverse sections.

In the drawings the plate cylinder is shown as formed of two similar "ransversc sections 1*, 1 (see Fig. 3) which extend from the center outwardly. The inner ends of these sections 1 are axially bored to receive a steelshaft 3, which is disposed axially of the sections-Q13, 1 and connects and supports the inner ends thereof. This sh aft 3. is journaled in a cylindric bearing 1, which has a smooth runningfit against the ends of the cylinder sections l The. bearing 1 is connected by anarrow web portion 1 with a base portion 4-. anu the bearing web and basemay be formed integral of steel, or other suitable metal, as indicated in Fig. .5 5 the web 1 canbe formed by cutting circular grooves at, in opposite sides of the block, sufliciently wide to afford clearance for the portions of the inner ends of the sections 1 or parts connected. therewith, which overlap the ends of the bearing 1; as indicated in Fig. 3. 'This web connection between the bearing 4 and thebase J. in very strong and stiff and is not liable to spring or deflection because of its peculiar shape.

To facilitate assembling the parts thebearing 1 might be cut in half as indicated in Fig. 4-, the detachable half 4* of the bearing being rigidlyfastened to theother half of the bearing by tap bolts 4 as indi-' cated in the drawing.

The bearing 1 is supported directly in the axial line of the plate cylinder by anysnitaof the machine adjacent the plate cylinder (see Figs. 1 and 2), the base 1 of the hearing being secured to the inner side of this tie bar by any suitable means, bolts being indicated in the drawings.

Preferably tie 6 is cast hollow and has upper, lower and intermediate horizontal walls 6", 6 6 as indicated in Figs. 2 and 4t; and I prefer to make the tie about four times as wide as the diameter of the plate cylinder. This tie (S is secured between the side frames of the press in any suitable in anner, and preferably so that it lies practically horizontal and in the plane of the axes of the cylinders 1 and 2 and its inner side closely adjacent the plate cylinder 9 so that the impression thrust of the impression cylinder 2 is transmitted through the plate cylinder 1 and bearing l direct-.11 to the tie (5; such tie being sufficiently strong to withstand any practical impression pressure without deflection.

Thelarge tie 6 not only serves to support the intermediate bearing of the plate cylinder, but also serves as a convenient support for the inking mechanisms for the plate cylinder. The ink fountain, the ink (ll'lHH and system of inking rollers for the plate cylinder 1 may all be mounted upon the related tie 6 as indicated in Fig. 2. The inking mechanism may be like that shown in my Patent No. 1.3014191, of April 22, 191$), or of any other suitable kind and forms no part of the present invention.

The ends of the shaft sections 1. may be recessed to receive the .bushing, or the adjacent ends of the sections 1 may be reduced as at 1 to the diameter of the lnishing -l: and hardened steel bands 5 may be fitted onto the reduced ends 1 of the sections 1 and. secured thereto by any suitable means. said bands 5 projecting over the adjacent ends of the bearing L and almost conta ting with the web at of the hearing, so that the inner ends of the adjacent plates P project over the ends of the hearing l and are only separated by the usual and necessary margin required between side by side i1nprcs sions on the web or sheet.

The bands 5 are preferably made of similar opposite halves and securely 'lastcncd to the reduced ends 1 of the parts i by screws Fr; and these bands 5 may be provided with internal annular ribs 5 engaging corrcsponding annular grooves in theTeduccd inner ends 1 of the sections 1. The inner ends of the bands 5 or the sections 1 may be provided with exterior flanges 5 against which the inner ends of the two inner tubular plates P abut. as indicated in the drawing.

The plate-cylinder is thus provided at the point where it is most liable to spring when 1,431,454 V jjj rotated at high speed or yield underimpression'pressure with a solid substantial hearing by which the plate cylinder is absolutely prevented from springing or yielding. With this invention 1 am able to build tubular page plate cylinders four or more pages in length and to successfully operate them at any desired speed Without any disadvantageous results or effectson the product due to springing or yielding of such cylinders; as the tendency of the long cylinder of small diameter to spring athigh speed or to yield under impression pressure is entirely overcome. a

Furthermore I am enabled to make single page tubular plate cylinders fouror more pages wide, and to slip the tubular. plates thereon either from one or both ends, and

to have the plates spaced equally apart, and yet provide an intermediate bearing for the plate cylinder, which bearing issupported exterior to the plate cylinder by a web which is less in width than the necessary margin between adjacent impressions on the web.

' Furthermore by this invention with one tubular impression cylinder Ican print a web four or more pages wide before slitting it. Further by printing such wide webs I am enabled to greatly reduce the number of printing couples and inking mechanisms required in the forms of presses shown in my Patents Nos. 867,230 and 1,240,008 aforesaid. it i a a a This invention also enables me to print a four or more page wide web with singlepage-tubular plates, without severing the web prior to the printing thereof, which is a great advantage, insuring uniformity of travel of the web and proper positioning of the various impressions upon the web.

. In the drawings I have simply shown one printing couple comprising a plate and impression cylinder and connecting mechanism, as the present invention relates particularly to the construction and support of the plate cylinder. In a perfected mechanism, such plate and impression cylinders will be dupli cated; and in a large press any desired num ber of'such printing couples, orperfecting mechanisms thereof can be employed according to the desired total capacity of the press.
